Title: Method for evaluating water retentivity of paper coating solution
Inventor: TSUNEKAWA KENJI
IPC: G01N25/20
Filed: 1991-03-08
Abstract: PURPOSE:To automatically and efficiently perform measuring operation by obtaining an endothermic curve by the thermal analysis of a paper coating solution sample and detecting the presence of two separated endothermic peaks in the endothermic curve to evaluate the water retentivity of the sample. CONSTITUTION:An endothermic curve 1 is obtained by the thermal analysis of a paper coating solution sample. In this endothermic curve 1, a first endothermic peak A is present at a point of about 44 deg.C and a second endothermic peak B is present at a point of about 80 deg.C and the max. value C is necessarily present between both peaks A, B. The water content Wc and evaporated moisture quantity Wf in the sample at this peak C are calculated on the basis of a wt. change curve 2 and, further, the ratio R% of the water content Wc and the water content Wi before analysis or the ratio P% of the water content Wc and the quantity Wf is calculated to obtain a water retentivity evaluation index. The index, the R-value and the P-value display the water retentivity of the paper coating solution with extremely high reliability. Since a thermal analyser is used as a measuring apparatus, measuring operation can be automatically performed with good reproducibility.

Title: Functional copper alloy
Inventor: SAWADA KAZUO
IPC: C22C9/00
Filed: 1980-05-24
Abstract: PURPOSE: To provide functional characteristics such as a shape memorizing effect or superelastic behavior by preparing an alloy composition consisting of a specified amount of Al, a specified amount of Zr and the balance Cu.  
     CONSTITUTION: This alloy consists of 9W15wt% Al, 0.003W0.3wt% Zr and the balance Cu. In order to control the usage temp. zone where a functional effect is produced, it is desirable to add <10wt% Ni besides said elements. The reason why the Al content is regulated to 9W15wt% is that the alloy can not form a β-phase structure even at high temp., and no shape memorizing effect and no superelastic behavior are produced even by heat-treating the alloy when the Al content is out of the range. When the Zr content is <0.003wt%, the effect of improving the functional characteristics is insufficient, and >0.3wt% Zr causes a change in the transformation temp. zone.

Title: Filament locus forming device
Inventor: NISHIDA ATSUSHI
IPC: B29C70/16
Filed: 1993-03-29
Abstract: PURPOSE:To enhance working efficiency by forming the locus of the optimum filament generating no slippage in a filament winding method. CONSTITUTION:When winding data and filament data are inputted to a CPU 1 from an input device 2, the CPU 1 reads a mandrel shape from a first RAM 4 to input the same to a locus calculation part 11. The locus calculation part 11 sets the division elements of a mandrel to cut the mandrel crosswise and two-dimensionally develops the respective division elements to form the straight line corresponding to a winding angle and restores the division elements to three dimensions to calculate one reciprocating filament locus free from slippage. A winding start position determining part 12 sets an angle of rotation required in one reciprocation and calculates the reciprocating number of times necessary for perfectly covering the mandrel with a filament on the basis of the radius of the mandrel, the width of the filament and filament overlap width. Thereafter, the calculation of a start position and the correction thereof are performed and the optimum filament locus of one layer is calculated to be displayed on an output device 6.

Title: Radio frequency filter and method for adjusting its frequency response
Inventor: LOUKKOLA JUKKA
IPC: H01P1/205
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain small resonator filter structure which is used for multiple purposes by forming a pattern in an area between the short-circuit ends of the resonators. SOLUTION: The internal conductors of the respective resonators are condutively connected to grounded potential at the end surface of filter structure through stripe areas A1 and A2. The stripe areas A1 and A2 are mutually connected in the stripe area A12. Then, a low surface is plated with conductive plating. The plating is removed or added, as necessary, for obtaining a desired characteristic. That is, a material is removed from the stripe area A12 of the pattern is order to affect the connection of the resonators, so that the inductance between the resonators is made to be large. When the characteristic frequency of the resonators are desired to be made higher, the conductive material is added to the stripe areas A1 and A2 of the formed pattern, so that an effective serial inductance with respect to a ground connected to the resonator is reduced.

IPC: G06K9/20
Filed: 1990-03-20
Abstract: PURPOSE:To accurately read characters by using the two-dimensional fractal matrix of a multilevel picture to classify a texture pattern and extracting a character area. CONSTITUTION:A multilevel picture 5 consisting of a background area 3 and a character area 4 having characteristic texture patterns is inputted from an image pickup device 1 to a character reader 2. A rectangular coordinate system of (x) and (y) is considered and the density value at each point of the picture is read on the (z) axis to obtain the multilevel picture which has a picture surface 6 of a curved surface corresponding to the density value. The character reader 2 operates the trace value of the two-dimensional fractal matrix and the value of a determinant based on inputted picture data and uses the difference in texture pattern between the background area 3 and the character area 4 based on both operated values to extract the character area 4. A character is recognized in the extracted character area 4. Thus, the character is accurately read.

Title: Infrared tracking device
Inventor: SUGAWARA KIYOSHI
IPC: G01S3/781
Filed: 1988-03-24
Abstract: PURPOSE:To improve disturbance resistance and clutter resistance by providing two infrared detectors which have different sensitivity characteristics, an arithmetic processing part, a storage delay circuit which uses its arithmetic result as a reference value thereafter, and a discriminator. CONSTITUTION:Filters 12 and 13 have maximum sensitivity at different wavelengths lambda1 and lambda2 and total sensitivity curves of the outputs of the detectors 14 and 15 are f1(lambda) and f2(lambda). When the reception spectrum from a target body is g(lambda), the outputs Sa and Sb of the infrared detectors 14 and 15 are integral g(lambda)f1(lambda)dlambda and integral g(lambda)f2(lambda)dlambda. Therefore, when a target is scanned, a spectrum ratio signal is sent out to a storage delay circuit 18 through a gate circuit 17 as the output of a divider 16 when the target body is decided from the current discrimination result, so that the signal is led out as a reference signal r0 a certain time later. A divider 19 divides a signal r0 having time delay by the current spectrum ratio signal of a divider 16 and its output aT is compared by a comparator 20 to open or close gate circuits 17 and 22 according to the comparison result.
